What type of car batteries is the best to have?

When choosing a car battery, many car owners can’t seem to decide which type of a battery to choose. Is it better to have the battery that’s possible to maintain or is it more advantageous to have a maintenance-free car battery? What’s the difference between these batteries? Let’s talk about these types of batteries as well as about their differences in order to see which car battery is the best to buy in your case.

What’s the difference between these 3 types of car batteries?

Based on the way the batteries are named, it’s obvious that there are batteries that require maintenance and there are batteries that doesn’t require it.

Maintained (Serviced) Car Batteries

As for the batteries that require maintenance, it should be pointed out that it’s almost next to impossible to buy such like batteries as well as buy a car with such a battery. These batteries allow a car owner to replace the plates of battery’s jars in case there occurred a short circuit between the plates. The thing is that the majority of car owners prefer buying a new car battery instead of bothering to replace the plates. Alternatively, it’s possible to have a battery replaced for free (in case the warranty is still valid). That’s why maintained batteries are not popular nowadays.

Low-maintenance Car Battery

Low-maintenance batteries are the batteries that require a car owner to check the level of charge, the density of the electrolyte and the level of electrolyte. If necessary, a car owner (or the person you come to have your car battery checked at a service center) can add distilled water or electrolyte in the battery. However, it’s impossible to replace the elements inside a car battery itself.

What is a maintenance free car battery

Maintenance-free batteries are the batteries that don’t require any additional maintenance. Due to the fact that such like batteries are non-spillable, it’s not recommended to open them up.

Advantages of maintenance-free car batteries

The first and the biggest advantage of such like batteries is that there is no need to check anything. All you need to do is simply use your battery.

The second advantage is that the service life of this battery is longer than the service life of a battery that can be maintained. This is due to the fact that the battery is non-spillable. Consequently, water doesn’t evaporate out of it.

One more thing that makes such like batteries different from the batteries that can be maintained is that they manage to keep their charge for a longer period of time when not used. According to statistics, maintenance-free batteries loses only 2% of charge within one month whereas the batteries that can be maintained lose up to 20% of charge when not used. That’s why the car owner that uses maintenance-free battery will always be able to start the engine from the very first try even if he had to leave his car parked for some time.

Since it’s forbidden to open up maintenance-free batteries, you can always bring your battery to the service center in order to fix it if necessary. Mind that it’ll be fixed for free. As a rule, you also need to have the check confirming that you bought your battery at a store and a valid warranty. If it’s impossible to fix the issue with your battery, you can simply bring your battery back to the store where you bought it and get a new battery (the same model) for free. As for the broken battery, it’ll be diagnosed in order to find out whether or not it’s possible to fix.

Disadvantages of Maintenance-free Car Batteries

The biggest disadvantage is the price. In fact, maintenance-free batteries have a higher price than low-maintenance batteries.

If you decide to charge your maintenance-free battery, you need to take this procedure seriously. The thing is that such like car batteries should be charged from the source that provides direct voltage without any changes in the current. The voltage should amount to 13.9-14.4 V when charging. Besides, it’s forbidden to overcharge such batteries.

Consequently, we can come to the conclusion that it’s impossible to charge maintenance-free battery using the tools “you have at hand” or by connecting it to a different car. You’ll have to buy a special charging device that provides direct current during the process of charging.

If there is something wrong with the electrical system of your car, the maintenance-free battery you use may get broken very fast.

Due to the fact that such like car batteries don’t charge that well from the generator when it’s cold outside, it’s recommended to charge maintenance-free batteries more often during winter.

Experts say that during the warm seasons of a year it’s necessary to charge maintenance-free battery once in 4-5 months. If it’s wintertime or you live in a place where the climate is cold, you’re to charge your battery once in 2 months.

Advantages of Low-maintenance Batteries

– Price. low-maintenance batteries cost less than maintenance-free batteries.
– It’s possible to check the condition of the plates as well as check their colour. It’s also possible to check the level and the density of the electrolyte and take necessary measures if there occurs a need to do so. Actually, those car owners who have no desire to maintain the batteries installed on their cars, may find this to be a disadvantage.
– If you know how a car battery functions, by maintaining it the right way you have all the chances to prolong its service life.

Disadvantages of Low-maintenance Batteries

– The battery is not non-spillable. Consequently, the water can evaporate from it. It means that you’ll have to regularly check the level of the electrolyte.
– It’s not recommended to totally discharge such a battery because it may result in its service life being significantly reduced.
– Such like batteries in comparison with maintenance-free batteries lose their charge faster when not used.

Of course, it’s always up to a car owner to decide what battery to buy. We believe that if it’s about the battery for a new car, it’s better to buy maintenance-free battery. However, if you have a car that was manufactured in the 90-es or the beginning of the 2000s, it’s better to buy a low-maintenance battery.
